The GIMP is a very powerful application. For those of you that are used to photoshop, it is maybe worth downloading Gimpshop (see Gimpshop for the linux version). Gimpshop is a hacked version of gimp that looks and feels like photoshop, so that people used to photoshop (or photoshop pirates) can migrate easily :) "If you'r used to gimp, keep it as it is - if you'r used to photoshop use gimpshop"
The Windows version of GIMP can be downloaded from http://gimp-win.sourceforge.net/stable.html, it's a 11 megabyte download: no reason not to try it.
The Gimp works well, and cuts its mustard. Only in very rare case (maybe a marketing department with very complex color handling) will anyone miss photoshop. MANY photographers now use the gimp (Gimpshop exists for MACs, Windows and Linux)
Maybe it would be useful to download the user manual as well :-)
